The fledgling nature of microservices means that the tooling around developing, testing, and deploying microservices is still immature. Our initial design for the API will be simple, we will need 1 endpoint to target and 1 model to represent the type of object we are returning. We need to secure the routes that allow people to create/update or delete so that only authorised users can access these routes.
